OVEN BURNER.

To all whom it may concern Be it known that I, FREDERIC G. NIooLAUs,

a citizen of the United States, residing at an oven burner, of aconstruction adapted particularly for use with an oven heat'regu 'lator,such as shown and described in the Meacham Patent No. 1,236,335, datedAu-. gust 7th, 1917.

This invention consists of a gas burner adapted to burn in an invertedposition, that is, the burner jets are in the under side of the burnergas conduits and the flame projects downward.

The flow of gas to a burner used with an oven heat regulator, of thetype shown in the Meacham patent, is controlled by a thermostat-ic valveand at times the flow or head of gas is very low and therefore causing aslow leakage of gas through the ports or jets. When the gas flow orpressure is low, I have found that in gas burners of the: typeheretofore used, that some of the jets do 'not light but dischargeunconsumed gas into the oven.

To overcome the disadvantages of the old type of burner which operatesas above described, I have arranged the jets or ports in my burner in achannel which conducts the gas issuing from an unlighted jet, to onewhich is lighted and thereby causes the gas to flash back to theunlightedjet and cause it to burn at its port.

The object of my invention is to provide a gas burner in which all thejets will be light ed from a pilot no matter how low the gas pressuremay be, due to the action of the thermostatically controlled gas valve.

A further object of my invention is to provide a gas burner which ischeap and simple of manufacture, and which is economical and efficientin use.

In the drawings t Figure 1 is a perspective view of my improved gasburner showing the arrangement of the jets.

Fig. 2 is a vertical sectional view on the line22 of Fig. 1, looking inthe direction indicated by arrow.

'Fig. 3 is an enlarged plan'view of one corner of the'burner, showingthe arrangement of the jets in the gas conduit across one end of theburner.

Fig. 4 is an enlarged fragmental sectional view through the gas conduitacross one end of the burner.

Referring now to the drawingsin which like parts are designated bysimilar referencenumerals, A is agas burner adaptedffor use 111M311oven. of a .gas stove. In the embodiment here shown the burnerisrectangular in shape and is provided with two hollow end gas conduits1 and 2, which comprise the ends'of the burner and three hollow gasconduits 3, 4 and 5, which join and are in communication with the endconduits at the ends and centers thereof respectively.

A as inlet connection 6 is provided in the supp y end conduit 1 and theoppositeend conduit 2 is provided with ears 7 The burner A is supportedin the oven 'by means of the gas inlet conduit or pipe (not. shown)which connects to the burner at 6 and the ears 7, which are suitablyfastened to or supported by the oven. To strengthen the burner and toprovide against possible warping due to being subjected tosudden heatingand cooling, I have provided center braces 8 between the conduits 3, 4.and 5.

The burner jets or ports 9 are in communication with the conduits, .asshown, and are located in two'parallel rows in the inner side walls ofthe V-shaped channels 10, which are in each edge of the conduits 3, 4,and A 5. are on its inner edge only and are similarly located in aV-shaped channel 12, but in the channels 10 in the conduits 3, 4t and 5,are in communication with the channel 12,

in the end conduit2, while the opposite end supply conduit 1 carries nojets.

By arranging the jets in channels 1n this manner, I have found that whenthe burner The jets 11 in the end. conduit 2 is operating under a lowhead or pressure of gas, that if one or more of the'yets fails to lightthe gas will flow alon the channel un til it reaches a jet that islighted and there will then take place a flash which will igniteformerly unlighted jets. It will be under.-

stood that the burner is in an inverted posi;

tion in the oven and that any gas escaping from an unlighted jet willrise, being lighter I19 than the air in the oven, against the botttom ofthe V-shaped channel into which it'is issuing and will flow along thisuntil it reaches a lighted jet, at which time the flash above referredto will take place.

In the preferred form, my 'burner is cast in one piece, but it will bereadily understood that this practice could be departed from and thatother changes might be made without departing from the spirit of myinvention.

Having thus described my invention, what I claim and desire to secure byLetters Pat ent is 1. A single burner conduit having a gas conveyingchannel located in the edge of the outer face of its bottom wall and anexit opening connecting the conduit and the said gas conveying channel,for the purpose described.

2. A single burner conduit having a gas conveying channel formed in theouter face of its bottom wall, and at the edge of said bottom wall, thebottom wall having a gas exit extending at an angle through the bottomtowards the side wall'of the conduit, whereby the gas flame is projectedinto unobstructed space beyond the side wall of the conduit. I

3. A single burner conduit having two channels formed in the outer faceof the bottom wall of the conduit, the respective channels located inthe edges of the bottom wall of the conduit, the bottom wall of theconduit having divergently and outwardly extending gasexitscommunicating with the 1,4.1c,5oo

channels and with the conduit, whereby the flames from the exits areprojected beyond the side walls of the conduit, for the purposedescribed. 7 a

4. A burner having transverse and longitudinal gas conduits, theconduits provided with channels at their edges separated by centralraised portions, and exits extending into the channels adjacent theintersection of the raised portions with the channels, for the purposedescribed.

5. A burner composed of transverse and longitudinal hollow conduits,cast integrally, gas exits adjacent the edges of the conduits, and gasdistributing channels formed in the edges of the conduits communicatingwith the exits, whereby the gas is directed as described.

6. A burner composed of longitudinal hollow conduits having their endsclosed and connected by transverse conduits, channels formed in theedges of the outer faces of the conduits, and exits in the conduitscommunicating with the channels, for the purpose described. 7

'7. A burner composed of transverse and longitudinal hollow conduits,gas exits adj acent the edges of the longitudinal conduits and the inneredge of the transverse conduit, and gas distributing channels formed inthe edges of the longitudinal conduits and the inner edge of thetransverse conduits, whereby the gasis directed as described.

In testimony whereof I hereunto aflix my signature.
